In the game Action Fractions, you can practise adding and subtracting fractions.
The race starts off more simply adding fractions with like denominators, but becomes harder after round two when you have to add fractions with different denominators, and then subtract. Click on the image below to give it a go and let us know how you find it!
Today in class, some groups also worked on learning/revising the process for multiplying fractions. We used this video to work independently and help us with the concept. You can watch it below for revision.
On Friday, we continued our work on fractions, decimals and percentages. We started looking at how we could find the percentage of something when we had an amount that was more than or less than 100. To help us, we took to the school car park.
We found a row of 20 cars, and from this row were were able to work out some fraction, decimal and percentage amounts of the colours of the cars. Here is some of our work. We recorded it on the footpath so everyone could see.
This week’s episode of News from 56Chas been produced by Jarryd and Jessica. You can find out information about our class novel, interschool sports, what we prepared in Kitchen, our class inquiry topic and what we have been learning in Maths. Kelly will even share some examples of how to convert fractions into decimals and percentages. Check out the episode below!
In class at the moment we have been learning about fractional and decimal numbers and being able to convert between the two (for example, understanding that 0.42 is the same as 42/100). Today we were introduced to percentages and how they link to decimal numbers.
In class this week we have been exploring fractions, including what fractions are (equal parts of a whole or group), how to represent them and what they are equivalent to (the same as). We have been using a fraction wall to help us with this work. You may like to download this fraction wall for home to help remember how they compare.
Today as a part of our maths investigations we played the following game. It is fantastic for identifying and recognising fractions, and understanding/matching equivalent fractions. Everyone seemed to understand it really well!
To play, you can download the file I have created below and print it out at home. You will need two boards – one for each of the people playing. You will also need two 6-sided dice and a selection of counters or objects you can use to cover the squares.
Take turns to roll the two dice. Lets say you go first and roll a 2 and a 5. Using these two numbers, make a fraction (2/5) by placing the smaller number on top. As your fraction is 2/5, cover up two fifths on the gameboard. Now it is your partners turn to do the same.
The tricky bit is when the board starts to fill up. What if I roll 1/2, but I have already covered up both of the 1/2 pieces? You can start to match equivalents (cover 2 of the 1/4 rectangles, or 3 of the 1/6 rectangles). It works the same in reverse – if you roll 2/4 you can cover 1/2. You will also find you might get 4/4 but not have 4 quarters available to cover- you may need to cover the whole! You may also reach the stage where you have to skip a turn.
The winner is the first person to cover all the places on the wall.
Why not try playing this game at home and see if your child can explain it?
After playing the game we also went further to ensure we have an understanding of equivalent fractions and can compare fractions to see if they are bigger or smaller than one another. There are some games you can play online to help you practise these, including Fraction Frenzy, Tony’s Pizza Place and Melvin’s Make a Match.
This fractions game, Tony’s Fraction Pizza Shop, requires a number of skills to play. First, you need to ensure you read the instructions carefully when they come up on the screen. Your aim is to make as much money for the pizza shop as you can in 5 minutes. Secondly, you will need to know some equivalent fractions. Good luck!
Step 1.)Read the client order. A sample client order might read “I’ll have a large pizza, 1/2 pepperoni, 2/5 mushrooms and 1/10 bacon”
Step 2.)Select pizza size. In this case, select “large”. This will cause the denominator to change to 10, as a large pizza has ten slices.
Step 3 and 4.)Select toppings. First, click on pepperoni and apply to half of the pizza (5 slices). Next, click on mushrooms and apply it to 2/5 of the pizza (4 slices). Finally, click on bacon and apply it to 1/10 of the pizza (1 slice). NOTE – if you make a mistake, select a different pizza size and then re-select the original pizza size to get a new pizza.
Step 5) Click on “send”. If you are correct, you will make a sale. Incorrect pizzas will cost you! Enjoy the game!.
